If you drive Interstate 95 at night in southern Broward County over the coming weeks, expect to find multiple lanes closed.

You'll also do a lot of shifting to the right and the left and back again.

Starting Sunday, crews will begin re-striping southbound I-95 to shift traffic to the outside lanes for the next phase of the express lane project.

The lane closures will start at 9 p.m., with one lane closed between Hollywood Boulevard and the Golden Glades interchange. At 11 p.m., up to three lanes will be closed.

At least two southbound lanes will remain open at all times.

All lanes will reopen at 5:30 a.m.

The closures will occur each night Sunday through Thursday. But they are dependent on the weather. If it rains, the work will be postponed because crews can't re-stripe in the rain.

"The re-striping and traffic shift will take a few weeks to complete," said Tish Burgher, a spokeswoman for the Florida Department of Transportation. "When they get down south, then they will turn around and work their way north. They think they can do about a half mile per night."

Burgher said there are no plans to suspend the lane closures if the Miami Heat makes the NBA Finals.

"So far we have not seen any significant impacts during playoff games," Burgher said. "We will continue to monitor the situation with the understanding that the finals generate more traffic than the playoffs."

At Stirling Road and Hollywood Boulevard, traffic in both directions of I-95 is shifted to the median so crews can widen the overpasses. Similar work is planned at the Pembroke Road and Hallandale Beach Boulevard overpasses.

The $106 million project involves converting I-95's carpool lanes into express lanes between the Golden Glades interchange and Broward Boulevard. The Ives Dairy Road interchange also is being modified. Construction is scheduled to be completed in late 2014.

On May 21, the carpool restrictions were eliminated on I-95 between Sunrise Boulevard and Miami Gardens Drive. North of Sunrise Boulevard, the far left lane of I-95 in both directions is restricted to vehicles with two or more people, hybrids and motorcycles from 7 to 9 a.m. and 4 to 6 p.m. weekdays.
